this is rufus-scheduler 3.0, use .new instead of .start_new (RuntimeError)

Hi, Trying to get dashing running on windows ruby 2.0 On start of dashing I get the following. Apologies if this is a user error I am an absolute Ruby noob.

C:/Ruby200/lib/ruby/gems/2.0.0/gems/rufus-scheduler-3.0.0/lib/rufus/scheduler.rb:109:in `start_new': this is rufus-scheduler 3.0, use .new instead of .start_new (RuntimeError)

That's weird, because Dashing should be using rufus-scheduler 2.0 (as per https://github.com/Shopify/dashing/blob/master/dashing.gemspec).

If you installed Dashing via gem install then do

gem uninstall rufus-scheduler
gem install rufus-scheduler 2.0.24

and try again.

I'm closing this issue because it's not a rufus-scheduler issue, but let's go on with the conversation until it's solved.

Just as a note: Shopify/dashing#237 (the Dashing guys just added the restriction to rufus-scheduler 2.0, hence your version of the Dashing gem just points to whatever rufus-scheduler is at hand).

Hi, the supportive response very much appreciated. I sadly had no luck with the following outcome. I must mention again I am trying to get it working in Ruby 2.0 and on Windows.

C:\_projects\its_radiator>gem install rufus-scheduler 2.0.24
Fetching: rufus-scheduler-3.0.0.gem (100%)

***

Thanks for installing rufus-scheduler 3.0.0

It might not be 100% compatible with rufus-scheduler 2.x.

If you encounter issues with this new rufus-scheduler, especially
if your app worked fine with previous versions of it, you can

A) Forget it and peg your Gemfile to rufus-scheduler 2.0.24

and / or

B) Take some time to carefully report the issue at
   https://github.com/jmettraux/rufus-scheduler/issue

For general help about rufus-scheduler, ask via:

Cheers.

Sorry, it's my fault.

This install command should be:

gem install rufus-scheduler -v 2.0.24

I suggest you do a:

gem uninstall rufus-scheduler -v 3.0.0

beforehand so that 3.0 doesn't come back.

Please read http://github.github.com/github-flavored-markdown/ so that you can add markup to your issue requests from now on ;-)

Sorry again.
